create a variable STATIC_LINUX_SDK_NAME

[sebsto]

Extract the repeated _static-linux-0.0.1 suffix into a single STATIC_LINUX_SDK_NAME variable so it's defined once and reused across the install check, download, and build steps. Less copy-paste, easier to update if the version ever changes.

Added a function to select version 0.0.1 or 0.1.0

Update the STATIC_LINUX_SDK_NAME to version 0.1.0 to fix #242
